With the introduction of the new Jerry-YM thermal monocular, we thought it would be helpful to include a summary of key differences between it and the well-established MH25. While the MH25 V2 is substantially improved over the V1, the Jerry-YM does have some key improvements that are worth considering.
Jerry-YM Pros:
- Lighter weight (228g vs 315g)
- Accepts 18650s natively
- Includes a helmet-mounting solution out of the box (includes L4G24-style NVG mount and dovetail rail with adjustable IPD)
- "Scene" optimized thermal profiles (more testing required if these even make a difference practically)
- Comes in a hard case
- On-board compass and accelerometer
MH25 V2 Pros:
- Larger eyebox compared to the Jerry-YM
- Eyepiece does not articulate (Jerry-YM's eyepiece moves forward and backwards when adjusting diopter which forces you to move the device forwards and backwards to compensate)
- More intuitive controls via rotary wheel (click to NUC, turn rotary wheel to zoom)
- Better menu system and easier to operate overall (subjective opinion)
- Has audio recording capabilities
- Mini-rail mounting system on MH25 is more common (Jerry-YM has its own proprietary 3-hole mounting pattern which makes mounting on a bridge impossible without making an adapter)
- Better lens protection via the MH25's built-in iris system (Jerry-YM uses a rubber cap that is difficult to secure elegantly when using the device)
- Much better USB-C cable routing (if used with the KUULA-brand 180 degree USB-C cable); Jerry-YM is not compatible with 180-degree USB-C cables and will block the controls, essentially forcing you to route the USB-C cable forwards, creating a snag hazard
